Thanks...I'm curious to hear if anyone has had a different experience. I'm trying to find a good solution to importing/exporting using MOI since it can read iges files. The n-gon export to c4d, on the otherhand, seems to work well and I'm trying to figure pros/cons for working with a mesh in c4d to then export to maxwell.

n-gon support in an app is nothing else than handling triangulation within an n-gon shape without the user noticing it. C4D actually uses triangels to represent n-gons. You just do not see it. But you can make it visible.
